Bansadhara is your best bet. Close to the calm blue waters of the lake, during monsoons the water level rises and some areas are flooded, making for an island camping experience. You can take a walk while enjoying the green and sparse forest. At dawn, Bhandardara gives you the best value. It's also a great place to just look at the night sky, and you'll have the best stargazing experience ever. If you're travelling in the pre-monsoon season, it's firefly mating season, and millions of glow worms glow in the dark, making it look as if the stars have descended to earth. Enjoy the beauty and bounty of nature and its myriad experiences while camping near Mumbai in Bhandardara.
